Serial No. 612,845.

To all whom 'it my concern:

Be it known that I, JACOB S'rrnemrz, a citizen of the United States,residing vat Yonkers, in the county of Westchester and State of NewYork, havey invented certain new and useful Improvements in Safety-Razors, of which the following. is a specilication.

This invention relates to safety razors, and particularly to holders andblades for safety razors of that class using doubleedged blades.

The object of the invention is to provide a construction ofV holder andblade whereby the blade may be firmly held and quickly and convenientlyapplied and released, and whereby blades varying in thickness may beused and held withl an equal degree of firmness.

The invention consists ofthe features of construction, combination andarrangement of parts hereinafter fully described and claimed, referencebeing had to the accompanying drawing, in which:

Figure 1 1s a side elevation, partially in` section, ofa safetyrazor-embodying my invention. Fig. 2 is an endelevation of the same.Fig. 3 is a view similar to Fig. 1, showing the parts in position forthe release of the clamping plate and also showing in dotted lines theclamping plate thrown back to release the blade. Fig. 4 is a perspectiveview showing the blade removed and the clamping plate in open position.Fig. 5 is a horizontal transverse section through the stem and slidingcollar. Fig. 6 is a top plan view showing the blade tted in place readyto be clamped or removed, and with the clamping plate opened, a portiononly of said clamping plate bein shown.

Referring to the drawing, 1 1 designates .a handle carrying a reducedstem 2 -to which is secured a fixed base or guard plate 3 having combteeth 4 along its opposite longitudinal side edges. This plate isconcaveconvexly curved in transverse section with its concaved facesecured to the stem, so that the comb-toothed edges 4 curve inadirection toward the handle to ride smoothly over the surface to beshaved. At each end this plate 3 is provided with a pair of spacedcentral lugs 5. The blade' is of the doubleedged type, havin op ositelongitudinal cutting edges 7 an is a apted to rest upon the center ofthe convex face Aof the plate 3 and is provided at its ends with notches8 to receiveyand engage the lugs 5, whereby it is held centered withrelation to the plate 3. The' cutting edges 7 are arranged to cooperatewith the comb teeth 4 in the usual manner.`

The blade comprises a resilient, normally i fiat plate adapted to bebowed and held in position by a clamping plate 9 curved correspondinglyto the base plate 3 and adapted to be brought into position to clamp theblade along its longitudinal center against the longitudinal centralportion of the convex side of said base plate, the inturned edges 10 ofsaid clamping plateroperating to bear upon the blade adjacent to itscutting edges and to hold the latter rigid with relation to the combteeth. At its opposite ends the plate 9 is provided with inbentrightangular ears 11 and 12 adapted to project through the spacesbetween the lugs 5 and through the notches 8 in the blade and projectinwardly beyond the ends of the plate 3 when said plate 9 is in clampingposition.

The stem 2 is provided with outer and inner stop flanges 13 and 14, andmounted thereon for sliding movement between said flanges is a collar15, to one side of which is fixed the inner end of an oblique, arm 16,to the opposite end of which the ear 11 of the plate 9 is pivoted, asindicated at '17. At its opposite side the collar 15 is providedxwith akeeper or latch device comprising a pair of spaced latch hooks 18adapted to be engaged by a transverse latch bar 19 on the relativelyyinner end of a latch arm 20, which occupies an oblique positioncorresponding to that of the arm 16 on the opposite side of the stemwhen the parts are arranged in clamping position. The opposite end ofthe arm 2(),is pivoted to the ear 12 of the clamping plate, as indicatedat 21. By this construction it will be seen that the clampingv plate maybe swung to clamping position on its pivot `17 and drawn by means of thelatch arm into engagement with the blade, and the T-shaped end of saidarm interlocked with the hooks to hold said plate in clamping position.In this `operation the edges 1() of the clamping plate yield or `springto allow the bar19 to snap into the hooks and then react to hold saidbar in engagement with the hooks, such spring action of the edges 10placing them under tension to hold the cutting edges of the blade rigidagainst deiection.

The collar 15 is feathered to the stem for other part. Said collar isprovided with anexternally threaded lportion 24 engaged by an internallythreaded milledv adjusting sleeve 25 formed at its inner end with aninturned flange bearing against the stop flange 14, so that by turningsaid sleeve in one direction or theother the collar may be adjusted withrelation to the base plate 3 to regulate the clamping action of theplate 9 so as to adapt the same to clamp either thin or thick blades orto hold a blade with a greater or less degree vof bearing pressure,

vI claim:

l. A safety razor comprising a handle, a comb plate carried thereby, amember adjustable toward and from said comb plate, an arm carried bysaid member, a clamping plate pivoted at one end to the arm, a latchupon the adjustable member, a lat-ch arm pivoted to the freeend of theclamping plate and adapted to engage said latch member, and means foradjusting said adjustable member.

2. A safety razor comprising a handle, a member adj ustably mountedthereon, a comb plate carried by the. handle, a cooperating clampingplate pivotally connected at one end with the adjustable member, meansfor connecting the opposite end of said clamping plate With theadjustable member, and means for adjusting said adjustable member.

3. A safety razor comprising a handle, a concavo-convex comblate'carried thereby and provided at its-enfwith pairs of spaced lugs, ablade having end notches to receive and lengage the lugs, aconcavoconvex clamping plate having angularly bent ears to engage saidlugs and notches, an adjustable member on the handle, an arm fixed tosaid member and With which one of said ears of the clamping plate ispivotally connected, 'a latch device on said adjustable member, -a latcharm vpivoted to the other ear of the clamping plate and. adapted toengage said latch device, and means for adjust-ing. said 'adjustablemember.

4. A safety razor including a handle carrying a comb plate, a collarslidable toward and from said comb plate, spaced latch hooks on thecollar, an arm carried by the collar, a clamping plate pivoted at oneend to said arm, al second arm pivoted at one end to the free end of theplate andhaving a T-shaped free end to engage said hooks, and means foradjusting said sliding collar. In testimony whereof I afix my signaturein presence of two witnesses.
